Question

Вкладчик положил в сберегательный банк срочный вклад в размере 20000 руб. Процентная ставка, выплачиваемая сберегательным банком по этому срочному вкладу, составляет 18 % годовых. Какую сумму сможет получить вкладчик через 3 года, если банк начисляет простые проценты?

Answer 1

Ответ:

если банк просто проценты начисляет то

$20000 + (18 \times 3)\% = 30800$

а если каждый год к новой сумме, тоесть было 20к стало 23600, он уже ко второму числу процент даёт

$20000 + 18\% = 23600 \\ 23600 + 18\% = 27848 \\ 27848 + 18\% = 32860.64$

Answer 2

Calculation of Interest on a Fixed Deposit

To calculate the amount that the depositor will receive after 3 years on a fixed deposit with a principal amount of 20,000 rubles and an annual interest rate of 18%, we need to use the formula for simple interest:

Simple Interest = Principal Amount x Interest Rate x Time

In this case, the principal amount is 20,000 rubles, the interest rate is 18% per year, and the time is 3 years.

Using the formula, we can calculate the simple interest:

Simple Interest = 20,000 rubles x 18% x 3 years

Now, let's calculate the simple interest:

Simple Interest = 20,000 rubles x 0.18 x 3

Simple Interest = 10,800 rubles

Therefore, the depositor will receive an interest amount of 10,800 rubles after 3 years.

To find the total amount that the depositor will receive, we need to add the interest amount to the principal amount:

Total Amount = Principal Amount + Simple Interest

Total Amount = 20,000 rubles + 10,800 rubles

Total Amount = 30,800 rubles

Therefore, the depositor will receive a total amount of 30,800 rubles after 3 years on the fixed deposit.

Please note that the above calculation assumes that the interest is calculated annually and not compounded. If the interest is compounded, the calculation would be different.
